The alarming scope of Presidential power during an emergency

a really long article on what a President can do if they declare a national emergency.

(The rest of the article talks about historical precedent and a scenario of this being used by trump to end democracy)

Unknown to most Americans, a parallel legal regime allows the president to sidestep many of the constraints that normally apply. The moment the president declares a “national emergency”—a decision that is entirely within his discretion—more than 100 special provisions become available to him. While many of these tee up reasonable responses to genuine emergencies, some appear dangerously suited to a leader bent on amassing or retaining power. For instance, the president can, with the flick of his pen, activate laws allowing him to shut down many kinds of electronic communications inside the United States or freeze Americans’ bank accounts. Other powers are available even without a declaration of emergency, including laws that allow the President to deploy troops inside the country to subdue domestic unrest.

Unlike the modern constitutions of many other countries, which specify when and how a state of emergency may be declared and which rights may be suspended, the U.S. Constitution itself includes no comprehensive separate regime for emergencies. Those few powers it does contain for dealing with certain urgent threats, it assigns to Congress, not the president. For instance, it lets Congress suspend the writ of habeas corpus—that is, allow government officials to imprison people without judicial review—“when in Cases of Rebellion or Invasion the public Safety may require it” and “provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions.”

One power poses a singular threat to democracy in the digital era. In 1942, Congress amended Section 706 of the Communications Act of 1934 to allow the president to shut down or take control of “any facility or station for wire communication” upon his proclamation “that there exists a state or threat of war involving the United States,” resurrecting a similar power Congress had briefly provided Woodrow Wilson during World War I. At the time, “wire communication” meant telephone calls or telegrams. Given the relatively modest role that electronic communications played in most Americans’ lives, the government’s assertion of this power during World War II (no president has used it since) likely created inconvenience but not havoc.

We live in a different universe today. Although interpreting a 1942 law to cover the internet might seem far-fetched, some government officials recently endorsed this reading during debates about cybersecurity legislation. Under this interpretation, Section 706 could effectively function as a “kill switch” in the U.S.—one that would be available to the president the moment he proclaimed a mere threat of war. It could also give the president power to assume control over U.S. internet traffic.

The principle that the military should not act as a domestic police force, known as “posse comitatus,” has deep roots in the nation’s history, and it is often mistaken for a constitutional rule. The Constitution, however, does not prohibit military participation in police activity. Nor does the Posse Comitatus Act of 1878 outlaw such participation; it merely states that any authority to use the military for law-enforcement purposes must derive from the Constitution or from a statute.

The Insurrection Act of 1807 provides the necessary authority. As amended over the years, it allows the president to deploy troops upon the request of a state’s governor or legislature to help put down an insurrection within that state. It also allows the president to deploy troops unilaterally, either because he determines that rebellious activity has made it “impracticable” to enforce federal law through regular means, or because he deems it necessary to suppress “insurrection, domestic violence, unlawful combination, or conspiracy” (terms not defined in the statute) that hinders the rights of a class of people or “impedes the course of justice.”

In the past several decades, Congress has provided what the Constitution did not: emergency powers that have the potential for creating emergencies rather than ending them. Presidents have built on these powers with their own secret directives. What has prevented the wholesale abuse of these authorities until now is a baseline commitment to liberal democracy on the part of past presidents. Under a president who doesn’t share that commitment, what might we see?

So... What now?
